The reaction of
propene(CH3CH=CH2) with hydrogen atoms has been
investigated in a heated single-pulsed shock tube at temperature of 925-1078K
and pressures of 2-3 bar. Stable products from various reaction channels (H
atom addition and by inference H abstraction) have been identified and
quantified by gas chromatography and mass spectrometry. The reaction for the H
addition channel involving methyl displacement from propene has been determined
relative to the methyl displacement from 1,3,5-trimethylbenzene (1,3,5-TMB),
with k (1,3,5-TMB + H → m-Xylene + CH3) = 6.7 ´ 1013 exp(-3255/T)
